Eukaryotes are cells with nuclei and other organelles. not all of them use oxygen but some of them use oxygen to convert food into energy, which is a very efficient form of metabolism. These are aerobes or 'aerobic' eukaryotic organisims. these cells have most advance features they hold deoxy ribo nucleic acid (DNA) and another mitochondria that allows eukaryotes to generate energy using oxygen.
Cells convert nutrients into energy that is used for cellular activity. The reactions involved in this process requires a cell to break down the large nutrient molecules into smaller pieces, which produces energy as a product. In order to perform this function the cell requires a molecule that can accept an electron from a donor molecule produced in the breakdown process. As this electron is accepted by the oxygen molecule, energy is released. This is called aerobic cellular respiration.
EVOLUTIONARY PROCESS
Eukaryotic cells protect DNA in chromosomes with a nuclear membrane, make ATP with mitochondria, move with flagella and feed on cells which make our food with chloroplasts. All multicellular organisms and the unicellular Protists share this cellular intricacy.
The first eukaryotic cells - cells with a nucleus an internal membrane-bound organelles - probably evolved about 2 billion years ago. This is explained by the endosymbiotic theory. Endosymbiosis came about when large cells engulfed small cells. The small cells were not digested by the large cells. Instead, they lived within the large cells and evolved into organelles.
why do you think that most morden dat eukaryotes evolved to use oxygen? (consider evolutionary process...
From an evolutionary perspective, why do humans (and some, but not all other complex eukaryotes) senesce? Why do they slowly deteriorate with age, rather than staying perfectly healthy until eventually getting hit by a bus or eaten by a lion? Explain and explore one evolutionary explanation for senescence.

Which of the evolutionary forces do you think would have the biggest impact on population change? Why? In your answer provide one example (real or hypothetical)
which of the five steps in the strategic planning process do you think is the most important? Give an example of an industry where this would be the most important step. Do you think that a different industry might place more emphasis on another step in the strategic planning process? Why? (200 WORDS)
Why do you think voter turnout in the United States is lower than that of most well-established democracies in other nations? What do you think could be a way to increase voter turnout? Use facts to support your opinion.
Do you think bacteriophages are likely to be more or less diverse than prokaryotes? Than eukaryotes? Why? Is a plaque the result of the lytic or lysogenic pathway of the phage lifecycle? Explain. Why were you instructed to make three dilutions of the phage in this experiment? What purpose does this serve the experiment?
